Lots of questions

1. Do Illithid feed on something else except brains? I mean, h**l, a
human brain is quite small compared with most food items. Assuming a
squidhead needs one per day, an average illithid city (about 1100 heads)
would munch down two or three villages (not villageRs, villages)
quickly. And they live in the Underdark, with very few sources of food.
And the'yve got to feed the Elder Brain and the tadpoles. Is there an
alternate solution to the food problem?
2. What is Neogi culture like? IMC, I had the following explanation
[Neogi view slave-ownership a kind of perverted sport. In their view,
being able to efficiently control, manipulate, and manage a large group
slaves is a proof of one's intellectual and other virtues. Both the
number of slaves in one's care and the efficiency with which one manages
them are signs of status in neogi society. From a neogi stanpoint, it is
better to own slaves than gold or valuables.]
3. Are Illithids physically weak? How effective their slithery paws are anyway?
4. What are the main import/export goods the major planets/sphere
(Bralspace, Toril, Krynn, Greyhawk, ScroSpace, Vodoni, Beholders)? What
does the I.E.N. trade in? What do all those Sindiath Line ships haul?
5. Assume I pay an Arcane for a helm. Does the helm 'just appear out of
nowhere' or does he have to go/teleport to a different place and come
back to bring it to me?
6. What's the Illithiad?
7. Someone on the list mentioned that the Illithid trade with other
races, including some of the 'good' ones (humans, dwarves). What do they
have to sell and buy?
8. What are the populations of the major worlds?
